Objective To compare the sensitivities of the stimulation effect of human cord blood mesenchymal stem cells(CB-MSCs) and CB-MSCs of neuronal differentiation to lymphocytes(LCs) detected with carboxyfluorescein didcetate(CFSE) and MTT. Methods To prepare LCs from SD rat and divided into four group stimulating cells: 1. CB-MSCs;2. Dif-CB-HSCs;3. SH-SY5Y(positive control);4. Auto-LC(negative control).Stimulating cells were respectively Co-cultured with LCs. The proliferation of LCs was detected with MTT and CFSE ( n =3). Results CB-MSCs and Dif-CB-HSCs stimulated LCs to proliferate more weakly than positive control detected with MTT and CFSE. The quantity of proliferation of lymphocytes Co-cultured with CB-MSCs and Dif-CB-HSCs were higher than that of Auto-LC detected with CFSE. But MTT OD value of CB-MSCs and Dif-CB-HSCs was a little lower than that of Auto-LC. Statistical analysis results showed no significant difference.Conclusion CFSE can reflect proliferation status of lymphocytes better than MTT. CFSE shows more advantages in practical use.

Objective To measure the financial burden incurred by hypertension to urban patients in Beijing, Nanjing and Hangzhou cities. Methods Two communities were sampled from the three cities randomly, and 300 hypertension patients were sampled randomly from hypertension control files in each community for questionnaire survey. Results Health expenditure of the families with hypertension patients accounts for 14. 4% of the family's income, and 18. 2% of the family's expenditure, a ratio far beyond the national average (10.6 %). However, the majority of them report the burden as affordable.The basic medical insurance for urban residents helps alleviate the financial burden of hypertension patients and the extent of such burden has a close bearing on the outcome of hypertension treatment and prevention. Conclusion Effective community-based blood-pressure monitoring and control system is key to reducing the financial burden of hypertension. The reimbursement policy for hypertensive patients within the basic medical insurance is expected to be further improved.

Objective To establish stable HL-60 cell line with stable RYBP gene silencing using lentivirus-mediated RNA interference. Methods Five special shRNAs for RYBP gene were cloned to lentivirus vector.Recombinate lentivirus vectors were packed into lentivirus,which were used to infect HL-60 cells, and took empty vector and non-specific shRNA as control groups. Stable infected cells were selected with puromycin in 8 μg/ml concentration.The expression levels of RYBP were analyzed by Western blot,and confirmed the most effective RYBP shRNA.Then the level of mRNA was analyzed by real-time PCR.Results Stable infected cells were selected by puromycin successfully.Comparing to control groups,the expression of RYBP were reduced at different degrees (P ＜ 0.01). And RYBP shRNA2 took the most silencing effect, the RYBP mRNA was decreased by more than 95 ％ (P ＜ 0.05).Conclusion The shRNA2 targeting RYBP gene can effectively inhibit the expression of RYBP. HL-60 cell line with stable RYBP gene silencing were constructed successfully,which had provided experiment fundament for further studying the function of RYBP.
